Abstract
The purpose this paper is the development a novel polymeric fiber-optic magnetostrictive metal detector, using a fiber- optic Mach-Zehnder interferometer and polymeric magnetostrictive material. Metal detection is based on the straininduced optical path length change steming from the ferromagnetic material introduced in the magnetic field. Varied optical phase shifts resulted largely from different metal objects. In this paper, the preliminary results on the different metal material detection will be discussed. © 2010 SPIE.
